flutter 包 Youtube_Player_IFrame 不适合我

Question

我完全不知道自己应该做什么。我使用 youtube_player_iframe 中的示例代码来播放单个 YouTube 视频。我唯一改变的是 videoID。 这是我的代码：

import 'package:flutter/material.dart';
import 'package:youtube_player_iframe/youtube_player_iframe.dart';

class Project extends StatelessWidget{
  final String title;
  final String details;
  final String url;
  const Project(this.title,this.details,this.url,{super.key});

  @override 
  Widget build(BuildContext context){
      YoutubePlayerController _controller = YoutubePlayerController.fromVideoId(
        videoId: 'TYX3wGsKpwI',
        autoPlay: false,
        params: YoutubePlayerParams(showFullscreenButton: true),
      );

    return Container(
      height:400,
      child: YoutubePlayer(
        controller: _controller,
        aspectRatio: 16 / 9,
      ),
    );
  }
}

这是我热重新加载页面时遇到的错误：

The following assertion was thrown building Project(dirty):
Assertion failed:
file:///C:/Users/Emma%20Ude/AppData/Local/Pub/Cache/hosted/pub.dev/webview_flutter_platform_interface-2.10.0/lib/src/platform_navigation_delegate.dart:47:7
WebViewPlatform.instance != null
"A platform implementation for `webview_flutter` has not been set. Please ensure that an
implementation of `WebViewPlatform` has been set to `WebViewPlatform.instance` before use. For unit
testing, `WebViewPlatform.instance` can be set with your own test implementation."

The relevant error-causing widget was:

我正在创建一个 flutter 网站，而不是一个应用程序，所以我只需要担心它作为一个网站的工作。我尝试将 webview_flutter 添加到 pubspec.yaml 中的依赖项中，看看这是否有帮助，但什么也没发生。

youtube_player_iframe: ^5.1.2
  webview_flutter: ^4.7.0

我找出了问题所在。有人评论说要重建该项目，所以我也重新启动了我的计算机。现在可以了！
